The book came about after Mr Dazeley, 66, witnessed the destruction of Battersea Power Station over a number of years. He said: “I managed to get access to the power station in 2010 and took some amazing pictures of what is left inside it.

“The photos eventually went viral, and went everywhere, and that was like a light going on in my head - to photograph bits of London that I don’t know about and very few people have seen.”

Over the next four years he fought to get permission to photograph locations including The Bank of England and Ministry of Defence.

His book was published last year and proved immensely popular, with re-prints being ordered twice within the first two months, and making an appearance in the Amazon Top 100.
